Abstract
An apparatus and method of non-invasive blood pressure simulation uses a processor to calculate at least one transitory blood pressure envelope between an initial envelope representing an initial blood pressure and a final envelope representing a final blood pressure. The processor operates a pressure generator to create oscillatory pulse calculated by the processor from the at least one transitory envelope.
Claims20
A non-invasive blood pressure (NIBP) simulation device comprising:
- a user input device configured to receive at least one initial blood pressure value and at least one final blood pressure value;
- a processor that operates to calculate at least one transitory envelope from the at least one initial blood pressure value and the at least one final blood pressure value, and the processor calculates a plurality of oscillometric pulse pressures from the at least one transitory envelope;
- and
- a pressure generator operated by the processor to produce oscillometric pulses at the plurality of oscillometric pulse pressures.
A method of simulating a non-invasive blood pressure (NIBP) measurement, the method comprising:
- calculating a first envelope from at least one initial blood pressure value with a processor;
- calculating a second envelope from at least one final blood pressure value with the processor;
- calculating, with the processor, at least one transitory envelope from the first envelope, the second envelope, and a transfer function;
- calculating oscillatory pulses from the at least one transitory envelope;
- and
- operating a pressure generator to create the oscillatory pulses within an inflatable cuff.
A non-invasive blood pressure (NIBP) simulation device comprising:
- a user input device configured to receive initial blood pressure values and final blood pressure values;
- a processor that operates to calculate an initial envelope from the initial blood pressure values and a final envelope from the final blood pressure values, wherein the processor further calculates at least one transitory envelope using a transfer function applied to the initial envelope and the final envelope;
- a pressure transducer configured t pneumatically connect to an NIBP measurement cuff, measure a current pressure in the NIBP measurement cuff and provide the measured current pressure to the processor;
- and
- a pressure generator operated by the processor to create an oscillometric pulse in the NIBP measurement cuff, wherein a pulse pressure of the oscillometric pulse is calculated by the processor using the current pressure in the NIBP measurement cuff and the at least one transitory envelope.
